Abstract

The aims of this research was determined from yield analysis on the leaves extract of Sansevieria trifasciata and Sansevieria cylindrica. It was also determined by the presence of bioactive compounds that have the potential as antioxidants (phytochemical screening) on the leaves extract of S. trifasciata and S. cylindrica.The method used was a stratified extraction method with three types of solvent, ie non-polar solvent in the form of N Hexan; A semi-polar solvent of Aceton; And a polar solvent of Ethanol. The identification of six types of phytochemical compounds, the triterpenoid and steroid compounds, saponins, phenols, flavonoids, quinones and alkaloids. The result of rendement analysis showed that S. trifasciata yield was higher than S. cylindrica. The yield of S. trifasciata was 7.89 % and S. cylindrica 6.79%. The result of phytochemical compound analysis obtained three phytochemical compounds contained in S. trifasciata, named triterpenoid group compounds and steroids and flavonoids. Meanwhile, the results of the analysis of phytochemical compounds contained in S. cylindrica also obtained three phytochemical compounds, namely triterpenoid compounds and steroidal groups and alkaloids.

Abstract

Media is important in learning, especially with the development of science and technology. This study aims to design and develop a virtual laboratory based on web education as a learning media and to train the scientific attitudes of high school students. The type of research used in Research and Development (R&D) refers to the nine stages of Borg and Gall. The feasibility test of web education uses a validation questionnaire of material experts, language experts, media experts, and educator response questionnaires. The study results showed that material experts comprised 87.5%, language experts comprised 94%, media experts comprised 91.5%, and educator response questionnaires comprised 85.33%. So, web-educative biology is a very feasible category. The effectiveness of the media in training scientific attitudes is known to have an average n-gain value of 0.59 (moderate) for the experimental class and 0.39 (moderate) for the control class. Based on the results of the t-independent test, a sig of 0.00 <α value (0.05) was obtained, which means that H1 is accepted and H0 is rejected. It is concluded that the web-based educational Virtual Laboratory is effective in training the scientific attitudes of high school students and is suitable for use as a biology learning medium.

Abstract

This research aims to determine the increase in students' critical thinking skills (CTS) and sustainability awareness in SDGs issue-oriented climate change material using a problem-based learning (PBL) model. This type of research is quantitative research, the research design is quasi-experimental with a pretest-posttest non-equivalent control group design technique. The research sample consisted of two classes selected using purposive sampling technique. Research data was obtained by providing a pretest and posttest to determine the increase in CTS and an observation sheet to determine students' sustainability awareness data. The pretest-posttest scores in the experimental class using the PBL model obtained an average N-gain score of 0.52, including the medium category. The effect size test also obtained a value of 2.88 with the "large" criterion. The results of the sustainability awareness questionnaire data obtained an average percentage of 81.42% with a frequency of "often or always done". Based on these data, it can be concluded that the PBL model has a significant effect on improving CTS and influences sustainability awareness in climate change material that is oriented to SDGs issues. The use of PBL models can be an effective strategy in improving CTS and instilling sustainability awareness

Abstract

This study examines the effectiveness of the Problem Based Learning (PBL) model supported by the Android application ClimateClass in developing students' science literacy skills. Science literacy is crucial in the 21st century as it equips students with the necessary skills to make informed decisions in a technology-influenced society. Despite Indonesia's participation in international programs like PISA, the level of science literacy in the country remains low, indicating the need for innovative educational strategies. This quasi-experimental research used a pretest-posttest non-equivalent control group design conducted at SMA Negeri 1 Padang Cermin Pesawaran with a sample of 36 students from Class X.2. The intervention involved the implementation of the PBL model with the ClimateClass application to facilitate a more interactive and problem-solving-focused learning environment. Data were collected using a science literacy test and a questionnaire and analyzed using ANCOVA to determine the significance of the intervention. The results showed that the use of the PBL model supported by the ClimateClass application significantly developed students' science literacy, particularly in identifying scientific issues, explaining scientific phenomena, and using scientific evidence. Moreover, the study found no significant differences in science literacy achievement between male and female students, indicating that gender does not affect learning outcomes in this context. These findings highlight the potential of integrating digital media into educational models to create an equitable and effective learning environment in the digital era.

Abstract

This research aimed to develop an interactive e-module with hologram and text-to-speech technologies for teaching junior high school science, specifically the human excretory system, in grade VIII. Using an R&D approach based on the Borg and Gall model up to the 7th stage (problem identification, data collection, product design, design validation, product trials, and revision), the e-module was validated by six experts. The study involved students from SMPN 1 Bumi Ratu Nuban Lampung Tengah, including 10 students for small group trials and 30 students for field trials. The results showed that the e-module, with 82% validation from media experts, 92% from content experts, and 88% from language experts, was highly valid. Student trials also indicated that the e-module on animal tissue material was engaging, with a 78% rating in small group trials and 80% in field trials. This study offers a valuable contribution to enhancing education through innovative, technology-based learning media.
